9^2=6^2+x^2

解答

9^{2} = 6^{2} + x^{2}

解答

x = 35, x = - 35

+1

十进制

x = 6.70820 \dots, x = - 6.70820 \dots

求解步骤

9^{2} = 6^{2} + x^{2}

交换两边

6^{2} + x^{2} = 9^{2}

将

6^{2}

到右边

x^{2} = 45

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

x = 45, x = - 45

45 = 35

- 45 = - 35

x = 35, x = - 35

(2x-2)^2-4(2x-2)+3=0

(2 x - 2)^{2} - 4 (2 x - 2) + 3 = 0

5 p^{2} + 19 p + 12 = 0

(2x+3)(3x-4)=-5

(2 x + 3) (3 x - 4) = - 5

6 y^{2} = 19 y - 15

a (a + 24) = 0
